Big bold and beautiful! this plant needs lots of room! The square stems with opposing leaves that attach to the stems by wrapping around it forming a cup, hence the name. In our planting at the nursery the flowers are covered in pollinators and the birds drink from the "cups". Grows up to 10' tall in moist sunny sites but it still grows fine in average soil, just a little shorter (6').
